Chess Club Have you wondered what is the fastest possible mate in chess ? The professionals call it "Two-move checkmate". If you aren't careful you can easily get in trouble during opening stage. In this situation you are white and you are on the move. What is the one bad move you could make to have your king vulnerable enough so black can execute the "Two-move checkmate"? Answer of last month’s puzzle : In that world class game Bobby Fischer sacrificed his most powerful piece in order to win. He moves his queen to E8! At this point black quits. The well planned sacrifice forces black to capture using the rook on D8, which allows for the white bishop to checkmate moving to D5.
